In early 2022, various kinds of text messages were sent to over 100,000 residents of Brabant-Zuidoost who had not yet received a booster jab from the GGD. The results show that the most effective variant − in the 6 days after receiving the text message − led to a 3.2% increase in the number of vaccinations administered. This was the text message saying 'Jouw boosterprik ligt voor je klaar' (You can now book your booster vaccination) plus a randomly allocated date, time and location. Why…

While potential voters may register and intend to vote, many registered voters ultimately do not participate in elections. In addition, previous studies have not addressed how the impact of the text messages may vary among causal voters compared to habitual voters. Casual voters are defined as those who had previously only voted in the presidential election or major elections. Habitual voters are defined as those who have a higher propensity to vote (in this case, those who voted in each of the…

Behavioural science in the context of climate change at its related health risks has mainly focused on understanding and changing individual behaviours. However, effectively addressing the climate crisis requires broadening the focus on systemic societal change. This level of change is required to mitigate the negative effects of climate change as well as help people adapt to the associated (health) risks. Fostering systemic societal change requires situation-specific, large-scale data that can…

Using a place-based approach and working with profiled local communities in Coventry, we prototype and test a new experimental methodology with elements of design thinking to better understand barriers to engagement with retrofit measures designed to reduce household carbon emissions and alleviate fuel poverty. We partner with Coventry City Council, a local school and artists to deliver a pilot scheme in the Radford area of Coventry and aim in future to expand the project to additional areas…

'Returning to employment? Don't forget about your benefits!' When individuals receiving benefits return to employment having been registered as unemployed, it is important that they report the change in their income to the Benefits Unit on time, to avoid repayment demands. Why do individuals not comply with this notification requirement? And what interventions could improve compliance? A revised letter from the UWV Employee Insurance Agency and an additional page on the Benefits Unit website…

The study was conducted in collaboration with eight supermarkets from two of the largest Swedish supermarket chains. The stores provided the natural environment in which to conduct an experiment using real shoppers and real purchases, without shoppers being aware of the study. Four different interventions (different price displays) were designed, based on insights from behavioural science. These signs were tested in a randomised controlled study for two common and perishable vegetables –…

How does information on the job market affect the expectations and preferences of pupils in pre-vocational education? A large online platform for career development and career counselling provided pupils who were attending pre-vocational colleges with information on the career prospects of professions in which they are interested. This information resulted in pupils revising their expectations, and made them more likely to aim for jobs with better career prospects.

Five large cities in Noord-Brabant and the provincial authorities investigated how to improve cycling safety through behavioural interventions. They placed signs and markings along cycle routes in 's-Hertogenbosch, Breda, Eindhoven, Helmond and Tilburg. Half of the interventions had an effect; the number of dangerous situations decreased. Why this experiment was conducted: redesigning road layouts is not always possible Six locations in towns and cities in Noord-Brabant were identified as…

In Germany there are significant gaps in measles vaccination which lead to repeated outbreaks of the disease. Vaccinations do more than just protect the recipient against infection. They also protect people who cannot be vaccinated, for example infants or people with certain chronic illnesses. However, many adults do not know that they are not completely vaccinated against measles. In order to close this information and vaccination gap, wirksam regieren compared various possible ways to provide…

A campaign was launched to encourage young people to get the catch-up vaccination against Human Papillomavirus (HPV). The campaign succeeded in promoting discussion and increased awareness of HPV as well as persuading young people to get vaccinated. Why this experiment was conducted: provide boys and girls with a vaccine they might not have received In 2022 and 2023, boys were invited for the first time and girls were invited again to get vaccinated against the Human Papillomavirus (HPV). HPV…
